In response to these challenges, research in indoor occupant comfort has accelerated over the last twenty years. One of the many paradigm shifts has been the movement away from traditional, physically-based deterministic models due to their reported low accuracy (only 34%) across dozens of comfort studies in the past decades [1]}, [2]}. Recent research efforts have progressed towards adaptive comfort models [3]}, [4]}, [5]}, which rely on human behavior. According to these models, discomforting changes in the thermal environment are followed by a behavioral change in people to restore comfort. Such actions could include reducing individual activity levels or even opening a window. The main effect of such models is to increase the range of conditions that designers can consider comfortable, for instance, naturally ventilated buildings in the tropics where occupants have a higher degree of control over their thermal environment.
